To all whom, l may concern:

Beit known that 1,'HARRY E. LEE, a citi- Zen of the United States, residing at Oakland, in the county of Alameda and State of California, have invented new and useful Improvements in Rules, of which the following is a specification..

kn object of the Ainvention is to provide a rule consisting of few 'parts thatpcan be readily assembled and in which the scale or graduated pieces are effectively secured to the rule body and will present a neat and effective appearance. v

The invention contemplates, amongy other features, the provision of a rule commonly known as a carpenters rule `orlpocket rule,

and which comprehends sections forming the rule body, said sections having the scale pieces securedthereto `in a novel manner so as to insure accuracy in ther alining parts of the rule and result in' the rule having a neat and elfective appearance.

Still .further `objects of the invention reside in arule in which the scale pieces are so arranged rupon the body of the rule that they will itiiush with edges ofthe rule body'and can be quickly and 'accurately set in place to become rigid parts thereof.

y In the further disclosure of the invention reference is to be had to the accompanying drawings, constituting a part of this specification, in which similar characters of reference denote corresponding parts in all the views, and in which: e Figure 1 is a fragmentary Vplan view of the rule, looking at the front F ig. 2 is a fragmentary plan view of the rule, looking at the back; Fig. 3 is a fragmentary vertical longitudinal sectional viewshowing the maimer of attaching the scalefpieces to the body of the rule; Fig. t isa vertical longitu` dinal sectional view. taken on'thefline t-ff in Fig. 1; Fig. 5 is a fragmentary plan view of one of the sections with the scale pieceremoved; Fig. 6 is avertical transverse sectional view taken on theline 6,-6 in Fig. 1; Fig. 7 is a fragmentary perspective` viewof a modified form of rule bo'dygFig.' S is a vertical longitudinal sectional.v view taken through the structure shown in Fig. 7 'and Fig. Q'is' a verticalA transverse sectional view taken on the line 9-9 in Fig. 8.

Referring more particularly to the views, the rule body is indicated by the numeral 10 andrpreferably consists of hingedly connected sections 11 which may be inner or endl sections as desired. Each section 11 consists of a member l2 having a longitudinal groovel in its face, the member being substantially channel shaped so that sides 14 of the member will provide guides and Vform walls of the groove to permit of the insertion of a scale piece 15 into the groove of the rule body."

The' scale piece maybemade of metal, wood, ebony, vulcanite or any other desired substance, and preferably has each end cut away 'asat 16 to provide a reduced portion 17. p A cross piece 18 preferably formed with the rule body is provided at the end of each section and each'scale piece is of less i eng, thus providing a thick end and a thin .en

1n theapplication ofthe scale piece to the section, the thin 'end of the scale'piece'is inserted into the section so that the thin end ofthe scale piece will be received in the section between the body of the section and the cross piece 18, `thus permitting of inserting the entire scale piece into the groove of the section, after `which the scale piece is slid backwardly so that the reduced portion' of the thick end will extend lbeneath the other cross piece of the section and form a joint with the cross piece, whereby the upper face of the scale piece at the inner end will lie flush with the upper face of the cross piece, as shown in Fig. 4. l/Vhen this has been accomplished it will be seen that the thin end will have its cut away portion so arranged that the insertion of a securing block 20 into the outer end ofthe section to lie between the body ofthe section and the cross piece and extend into the groove, will cause the thin end of the cross piece to be raised so that the reduced portion of the thin end will fit against the inner edge of the cross piece and cause the thin end of the scale piece to have'its upper face lie flush with the face of the cross piece of the outer end of the section. To this end, the securing block is formed with a tongue 21 having a series of upwardlyprojecting inclined teeth 22, said tongue beingadapted to be of a somewhat wedge shaped construction so that when it is forced into the outer end of the section it will bearagainst theunder side of same time, the insertion of the securing block into thegroove and between the cross piece and body of thesection at its outer end will cause the teeth 22 to extend into the under side of the thin end of the scale piece and thus bind the block, whereby its end face 23 will fit flush with the transverse edges ofthe cross piece and section to provide a tight and solid end, as shown.

It will -be clearly seen that when the section, securing block and scale piece have been constructed as set forth the assembling of the parts is a simple matter and compre-` hends simply the insertion of the thin end ofthe scale -piece into the outer end of `the groove of the section, after which the scale piece ismoved baclrwaidly to have its thick end receivedin the inner end of th'egroove and .extend beneath the cross piece at'the inner end of the section. The securing block is then driven into place by inserting the same into the outer end Vof the section, thus causing the reduced thin end of the'scale to bear against the cross piece Vat the outer end yOlf the section and thereby rigidly secure the scale piece in position and'loclr the same in thegroove of the section. l

In F igs.v 7 to 9 inclusive I show a modi- Iiedform of section, rand in. which instance the 'section is indicated by the numeral 24 and forms one of the parts of the rule body, said section in this construction being of substantially an I-shaped configuration in cross section, as shown in Fig. 9, so as to provideanupper groove and a lower groove indicated by thenumerals 25 and 26, vrespectively. Into these grooves scale pieces 27 substantially similarto` the scale piece 15, are adapted to be arranged as shown in Fig. 8, the inner end of the section 2li being formedwithfa cross piece 28, one for the upper groove and one for the lower groove, andy beneath which a reduced end 29 of the scale piece is inserted. A cross piece 30is A then placed upon the outer end of the section to receive thereunder the reduced endV 31 andwhich Vis the other end of the scale piece, a rivetor other convenient securing member 32 being then passed transversely through the cross pieces Slat the outer end of the section to hold the outer ends of the cross pieces in rigid engagement with .the section sothat their faces will lie flush with the 'faces of the cross pieces.

Thus the scale pieces will be arranged upon the section of the rule body, with their edges and faces flush with the edges and faces ofthe section 'and the cross pieces thereon and,.as set forth in Figs. 7 to 9 inclusive, a, scale piece is arranged on each side of thesection and will have its inner face bea-ringagainst thesolid medial por- `tion of the section, andwhich extends longitudinally of said section.

Jing the scale pieces to the sections of the rule body and which can be readily adapted to the sections to present a neat andeifective appearance, and result `in the desired straight edges andjoints having, their edges fitting flush with each other and wherein scale pieces of various materials can be used in connection with the sections of the rule body when they are cut and formed as set forth.

It will be understood that I vdo not limit myself to the particular constructions set forth; that: various changes may beQinade withoutY departingfroml the spirit of the invention and that the scope of the Vinvention is defined by the appended claims.V

Having thus described'my invention, I claim: Y' Y, y.
